  1. OpenEmbedded as used by the Angstrom distribution Koen Kooi Texas Instruments Ltd.

  2. OpenEmbedded • Started in 2003 • Supports 254 devices, 32 TI based • Over 6000 recipes to build more than 2500 different apps and libs • Seperated intro distro, machine and image • Montavista and Windriver are OE based nowadays

  3. TI Device Support • OMAP™ - [ OMAP1, OMAP2, OMAP3, OMAP4] • omap1510inn, omap5912osk, omap1610h2 omap1710h3 • omap2420h4 omap2430sdp • nokia 770 nokia800 • omap3evm, beagleboard, omapzoom, omapzoom2 • cm-t35, omap3-pandora, omap3-touchbook, overo , palmpre • omap4430-sdp • Sitara™ AM - [Shiva] • am3517-evm • DaVinci™ DM - [DaVinci, DaVinciHD, Primus, Freon] • dm355-evm, dm357-evm, dm365-evm • dm355-leopard, neuros-osd • dm6446-evm, dm6467-evm, dm6467t-evm • davinci-sffsdr, neuros-osd2 • da830-omapl137-evm, da850-omapl138-evm, hawkboard

  4. Configuration management • You can make something machine specific by placing it in a subdirectory: • Or by specifying them in the recipe itself: ../linux/linux-omap-2.6.29/overo/defconfig ../linux/linux-omap-2.6.29/omap3evm/defconfig ../linux/linux-omap-2.6.29/beagleboard/defconfig ../linux/linux-omap-2.6.29/omapzoom/defconfig ../linux/linux-omap-2.6.29/omap3-touchbook/defconfig SRC_URI = "git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git;protocol=git” SRC_URI_append_beagleboard = " file://logo_linux_clut224.ppm “

  5. Angstrom • Started in 2006 • Is the reference for what a distro should be in OE • Over 6000 recipes to build more than 2500 different apps and libs • Build your custom rootfs online: http://www.angstrom-distribution.org/narcissus/

  6. Narcissus On-line Image Builder

  7. TI support in Angstrom and OE • TI gstreamer plugins for omap3, davinci, etc • SGX drivers and libs (1.4.14.2514), close collaboration with ASP gfx team • OpenGL|ES support for QT 4.5.2 • NEON optimizations for pixman and ffmpeg • Angstrom has everything compiled for armv7a on omap3 platforms

  8. TI support in Angstrom and OE • Good integration os dsplink/codec-engine thanks to close collaboration with component owners. • Various customers using it in production (e.g. Panasonic)

  9. Future • Closer collaboration with WTBU • Standardize on one OE ‘flavour’, namely Angstrom instead of different ones (e.g. Poky) • Integrate Braveheart stack
